Top Recommended Replacements
Bruno
FREEBest Overall Alternative for 2025
Why we like it
100% offline-first; stores collections as plain text files in your Git repo; no account or cloud login required; incredibly fast and lightweight; unlimited collection runs for free.
Keep in mind
Lacks the high-end API monitoring and 'public network' documentation features of Postman.
Insomnia
FREEBest for Design-First Development
Why we like it
Excellent support for OpenAPI specs and gRPC; sleek, modern UI; includes a 'local-only' mode to keep data out of the cloud; powerful plugin ecosystem.
Keep in mind
Some advanced features like Enterprise RBAC and centralized sync require a Kong Konnect subscription.
Apidog
FREEBest All-in-One Replacement
Why we like it
A true 1:1 Postman replacement that includes API design, debugging, mocking, and automated testing in one tool; much more affordable for teams; superior visual schema editor.
Keep in mind
Closed-source; cloud-reliant for its most powerful collaboration features.
Hoppscotch
FREEBest Web-Based Client
Why we like it
Runs entirely in the browser (or as a lightweight PWA); open-source; supports REST, GraphQL, and WebSockets; zero-friction for quick testing.
Keep in mind
Team collaboration features are still maturing compared to Postman; browser-based nature requires an extension to bypass CORS issues.
Yaak
FREEBest for Speed & Simplicity
Why we like it
Built by the original creator of Insomnia; focused on extreme performance; no telemetry; local-first; handles REST, GraphQL, and WebSockets.
Keep in mind
Newer tool with a smaller feature set; lacks complex automated testing suites.
Thunder Client
FREEBest for VS Code Users
Why we like it
Integrated directly into VS Code; very fast; supports environments and scriptless testing; no need to leave your IDE.
Keep in mind
The 'Free' version is now limited; collaboration features are locked behind a subscription.
HTTPie Desktop
FREEMost User-Friendly Design
Why we like it
The most beautiful and intuitive interface; makes complex JSON requests feel simple; great sync between the CLI and GUI.
Keep in mind
Lacks the deep automated testing and scripting power required for complex CI/CD pipelines.
